Comment 1 Chris 2019-09-22 02:10:27 UTC 
I would like to go ahead and note (since this is the report that I had just made), that Plasma has just crashed and hasn't loaded back in yet. I clicked the option to open this page after hitting "finish" in the bug reporter, and it crashed after firefox started loading. I am still in firefox though, but the entire system is just BLACK, besides this

Comment 3 Nate Graham 2021-03-09 03:23:13 UTC 
Looks like it's crashing in the graphics drivers. If this is still reproducible in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version), can you please report it to the Mesa developers? See https://docs.mesa3d.org/bugs.html

Thanks!
